Dieselwrencher thanks for the input. My issue with the ht3b is that it get too close to the oil filter. So if I decide to run it I will have to relocate the oil filter. It looks like you used a cummins part to relocate yours? What did you use for a filter housing and where did you mount it? If it ends up costing very much I will just go with a s400 series or possibly I nice s300 as a single.

Since were in topic What is everyone's opinion for turbo setup. My goal is 500-550 hp. Quick spooling and manageable egts. I will not tow with the truck very often just building it as a fun street truck. Twins are obviously more work but it seems that once you go over a 62/65/12 single spool up suffers greatly and a 62/65/12 will not make 500hp.
